GALLIUM CITRATE

Ga 67 INJECTION

FOR DIAGNOSTIC USE

DESCRIPTION

Gallium Citrate Ga 67 Injection is supplied in isotonic solution as a sterile, non-pyrogenic diagnostic

radiopharmaceutical for intravenous administration. Each milliliter of the isotonic solution contains 74

MBq (2 mCi) of Gallium Ga 67 on the calibration date, as a complex formed from 9 ng Gallium

Chloride Ga 67, 2 mg of sodium citrate, 6.8 mg sodium chloride, and 9 mg benzyl alcohol/mL added as

preservative. The pH is adjusted to between 4.5-8 with hydrochloric acid and/or sodium hydroxide

solution. Gallium Ga 67, with a half-life of 78.3 hours, is cyclotron produced by the proton irradiation

of enriched zinc oxide, is essentially carrier-free and contains negligible concentrations of other

radioactive isotopes.

The radionuclidic composition at calibration time is ≥99.89% Gallium Ga 67, ≤0.01% Gallium Ga 66

and ≤0.1% due to other radiocontaminants, each expressed as a percentage of total activity. The

radionuclidic composition at expiration time is ≥99.89% Gallium Ga 67, essentially zero (0.0002%)

Gallium Ga 66 and essentially zero of other radiocontaminants each expressed as a percentage of total

activity.

The chemical structure for Gallium Citrate is shown below:

External Radiation

The specific gamma ray constant for Gallium Ga 67 is 5.58 microcoulombs/Kg-hr-MBq (0.80R/hr-mCi)

at 1 cm. The first half value thickness of lead is 0.066 cm. A range of values for the relative attenuation

of the radiation emitted by this radionuclide that results from the interposition of various thicknesses of

Pb is shown in Table 2. For example, the use of 0.41 cm of Pb will decrease the external radiation

exposure by a factor of 10.

CLINICAL PHARMACOLOGY

Carrier-free Gallium Citrate Ga 67 Injection has been found to concentrate in certain viable primary and

metastatic tumors, as well as focal site of infection. The mechanism of concentration is unknown, but

investigational studies have shown that Gallium Ga 67 accumulates in lysosomes and is bound to a

soluble intracellular protein.

It has been reported in the scientific literature that following intravenous injection, the highest tissue

concentration of Gallium Ga 67 – other than tumors and sites of infection– is in the renal cortex. After

the first day, the maximum concentration shifts to bone and lymph nodes, and after the first week, to liver

and spleen. Gallium is excreted relatively slowly from the body. The average whole body retention is

65% after 7 days, with 26% having been excreted in the urine and 9% in the stools.

INDICATIONS AND USAGES

Gallium Citrate Ga 67 Injection may be useful in demonstrating the presence of the following

malignancies: Hodgkins disease, lymphomas and bronchogenic carcinoma. Positive Ga 67 uptake in the

absence of prior symptoms warrants follow-up as an indication of a potential disease state.

Calibration Time

Gallium Citrate Ga 67 Injection may be useful as an aid in detecting some acute inflammatory lesions.

CONTRAINDICATIONS

None known.

WARNINGS

Because of the benzyl alcohol content, caution should be used in administration to newborns,

particularly infants born prematurely, and individuals with impaired liver function.

The vial stopper contains dry natural rubber latex and may cause allergic reactions in providers or

patients who are sensitive to latex.

PRECAUTIONS

General

A thorough knowledge of the normal distribution of intravenously administered Gallium Citrate Ga 67

Injection is essential in order to accurately interpret pathologic studies.

The finding in an abnormal gallium concentration usually implies the existence of underlying pathology,

but further diagnostic studies should be done to distinguish benign from malignant lesions. Gallium

Citrate Ga 67 Injection is intended for use as an adjunct in the diagnosis of certain neoplasms. Certain

pathologic conditions may yield up to 40% false negative gallium studies. Therefore, a negative study

cannot be definitively interpreted as ruling out the presence of disease.

Lymphocytic lymphoma frequently does not accumulate Gallium Ga 67 sufficiently for unequivocal

imaging; and the use of gallium with this histologic type of lymphoma is not recommended at this time.

Gallium Ga 67 localization cannot differentiate between tumor and acute inflammation; and other

diagnostic studies must be added to define the underlying pathology.

Gallium Citrate Ga 67 Injection, as well as any other radioactive drugs, must be handled with care, and

appropriate safety measures should be used to minimize external radiation exposure to clinical

personnel. Care should also be taken to minimize radiation exposure to patients consistent with proper

patient management.

Radiopharmaceuticals should be used only by physicians who are qualified by training and experience

in the safe use and handling of radionuclides and whose experience and training have been approved by

the appropriate government agency authorized to license the use of radionuclides.

Carcinogenesis, Mutagenesis, Impairment of Fertility

No long-term animal studies have been performed to evaluate carcinogenic potential or whether

Gallium Citrate Ga 67 Injection affects fertility in males or females.

Pregnancy

Animal reproductive studies have not been conducted with Gallium Citrate Ga 67 Injection. It is also not

known whether Gallium Citrate Ga 67 Injection can cause fetal harm when administered to a pregnant

woman or can affect reproduction capacity. Gallium Citrate Ga 67 Injection should be given to a

pregnant woman only if clearly needed.

Ideally, examinations using radiopharmaceuticals, especially those elective in nature, in a woman of

childbearing capability, should be performed during the first few (approximately 10) days following the

onset of menses.

Nursing Mothers

Gallium Citrate Ga 67 Injection is excreted in human milk during lactation; therefore, formula feedings

should be substituted for breast feedings.

Pediatric Use

Safety and effectiveness in the pediatric population has not been established.

Geriatric Use

Clinical studies of Gallium Citrate Ga67 Injection did not include sufficient numbers of subjects aged

65 and over to determine whether they respond differently from younger subjects. Other reported

clinical experience has not identified differences in responses between the elderly and younger

patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low

end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac

function, and of concomitant disease or other drug therapy.

ADVERSE REACTIONS

Severe itching, erythema, and rash were observed in one patient of 300 studied.

The rare occurrence of hypersensitivity reactions or allergic reactions, skin rash, and nausea have been

reported in association with Gallium 67 use.

DOSAGE AND ADMINISTRATION

The recommended adult (70 kg) dose of Gallium Citrate Ga 67 Injection is 74-185 MBq (2-5 mCi).

Gallium Citrate Ga 67 Injection is intended for intravenous administration only.

Approximately 10% of the administered dose is excreted in the feces during the first week after

injection. Daily laxatives and/or enemas are recommended during the first week after injection until the

final images are obtained in order to cleanse the bowel of radioactive material and minimize the

possibility of false positive studies.

Studies indicate the optimal tumor to background concentration ratios are often obtained about 48 hours

post-injection. However, considerable biological variability may occur in individuals, and acceptable

images may be obtained as early as 6 hours and as late as 120 hours after injection.

The patient dose should be measured by a suitable radioactivity calibration system immediately prior to

administration.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to

administration whenever solution and container permit.

Waterproof gloves should be worn during the handling procedures. With a shielded sterile syringe,

aseptically withdraw the material for use. The expiration date of the drug is fourteen days after the date

of manufacture.

Radiation Dosimetry

The estimated absorbed radiation doses from an intravenous injection of 185 MBq (5 mCi) of Gallium

Citrate Ga 67 are shown in Table 4.
